Commute and Day Trips

On daily travel, Tandem+ provides a compact charging option with built-in USB-C and Lightning cables already attached. The display screen makes it easy to check remaining battery level before leaving or while in transit.

Charging Two Devices at Once

When both a phone and another device need power, Tandem+ can charge two devices simultaneously. This is useful for keeping multiple essentials powered from one battery pack instead of managing separate chargers.

Top-Ups While the Power Bank Recharges

Tandem+ is designed to charge two devices while the power bank itself is recharging. This setup helps when access to a wall charger is limited but several devices still need power.

Travel Packing with Fewer Cables

Because the USB-C and Lightning cables are built in, Tandem+ helps simplify your travel kit. The stated cable lengths of 18cm for USB-C and 15cm for Lightning keep charging connections close and contained.

Charging Small USB Accessories

Tandem+ is specified for charging earbuds, smartwatches, and other small USB-C, USB-A, or Lightning accessories. It works well as a shared power source for smaller everyday devices alongside phones and tablets.
